@drew.review: Astaxanthin vs. biotin—which one is better for beauty? ✨ Biotin is a B vitamin that supports keratin production and the normal maintenance of healthy hair, skin, and nails, especially when intake is inadequate. Astaxanthin works differently—it’s a powerful antioxidant studied for supporting skin hydration, elasticity, smoothness, and protection from UV-related oxidative stress. Think biotin for hair and nail structure; astaxanthin for skin aging and antioxidant protection. 🌿 #astaxanthin #biotin #hairhealth #skinhealth #healthyaging
